1.4.2. Making Installation Diskettes
You may need to create a diskette from an image file; for example, you may need to use
updated diskette images obtained from the Red Hat Enterprise Linux ES errata page
(http://www.redhat.com/apps/support/errata) or you may need to create a boot disk.
An image file contains an exact copy (or image) of a diskette's contents. Since a diskette contains
filesystem information in addition to the data contained in files, the image file is not usable until it has
been written to a diskette.
To start, you will need a blank, formatted, high-density (1.44MB), 3.5-inch diskette. You will need
access to a computer with a 3.5-inch diskette drive. The computer must be able to run either an MS-
DOS program or the
